Hello,we are working with a migrated system (from old APACS+/Intouch to new APACS PCS7).TheCPU is QUADLOG and the scada is WinCC and we also use IEM modules.Is it possible to monitor the IEM status (like a "lifebeat monitoring")?We need to show Good/Bad status of the IEM in a WinCC page.

See the IEM User Manual 10.1.1 Diagnostic and Statistics Data Tags available through any virtual APACS resource.

Example: In the Apacs channel create a tag named "PLC200_ID1.Gateway.Messages.PerSecond" where PLC200_ID1 is an IEMconnection you have configured. Then use this tag in lifebeat monitoring. If you are not using S7 to APACS, but just APACS to APACS via two IEMs then the statistics variables have the text S7 replaced with IEM. Example:S7toAPACS.Messages.Processedis insteadIEMtoAPACS.Messages.Processed. So you would use a tagsuch as PLC200_ID1.IEMtoAPACS.Messages.Processed.

I have not tried this myself. This is just based on my understanding. I hope it helps you.
